What is CVE-2021-41388?

The Netskope client for macOS versions prior to 89.x is susceptible to a local privilege escalation issue due to inadequate validation on new connections within the XPC implementation of the nsAuxiliarySvc process. This oversight allows low-privileged users to establish connections and invoke external methods defined in the XPC service, potentially granting them elevated privileges as the root user. This vulnerability exposes systems to significant security risks, highlighting the importance of timely updates and thorough security practices.
